STEAM-HEATED WATER-COCK.

SPECIFICATION forming part of Letters Patent No. 239,718, dated April 5, 1881.

Application filed December 31, 1880.

To all whom it may concern:

Be it known that I, J OHN BURNETT, of Oincinnati, Hamilton county, Ohio, have invented a new and useful Improvement in Steam-Heat- 5 ed Water-(Jocks, of which the following is a specification.

My invention relates to improvements in those water cocks or faucets in which the opening of the cock or faucet proper, so as to deliver water, is automatically accompanied by a discharge of steam, which, by mingling with the escaping water, operates to heat the same; and my improvement comprises a mechanical expedient whereby the attendant is enabled 1 5 to regulate at will the amount of the said antomatic steam-heating action, or to suspend its operation altogether. The heating device is so constructed as (after its adjustment as above) to require no further attention, being brought into action automatically by the simple act of opening the water-discharge, and being reduced to inactivity by the act of closing said discharge, without any special attention on the part of the user.

In theaccompanyingdrawings,Figurelis an axial section of my steam-heated water-faucet in its closed condition, the open condition of the water-valve proper being shown in dotted lines. Fig. 2 is a transverse section through the steam-inlet and its cut-oft, on the line 00. Fig. 3 is an axial section, showing a modification of myinvention. Figs. 4 and 5 are transverse sections on the lines y y and z z, respectively.

A may represent the barrel of a water cook or faucetembodying my invention; B, its waterinlet; G, its steam-inlet, formed with a perforated thimble, O, screwed into the butt-end of the barrel.

The operative stem D extends through a stuffing-box, E, and has a perforated and screwthreaded thimble or water-valve proper, F, which is tapped within a corresponding seat, G, in the barrel-wall. The stem D terminates inwardly in another thimble, H, which, in the closed condition of the cock, covers the'ports of the steam-inlet whenever the water-supp] y is shut off, and which (except when prevented by the hereinafter-described optional out- (No model.)

off) exposes said ports, so as to permit the entrance of steam and its access to the escaping water at the instant of discharge of the water, and in exact proportion to its rapidity,

To enable the attendant to regulate the amount of steam or to shut it oil altogether, the operative stem D is made tubular and is traversed by a central rod, I, whose inner extremity takes the form of a thimblc-formed cut-off, J, which occupies and snugly fits the interior of the steam-thimble G.

The cut-oft J has ports j, which, in one position of the operative rod 1, (see Figs. 1 and 2,) are opposite the blank spaces of the thimblewall O, and when the cut-off is in this position passage of steam is completely prevented, even although the automatic cut-oft H be retracted. From this position a partial rotation of the rod I brings the optional cut-01f ports into less or greater coincidence with those of the steam-thimble C, so as, on the elevation of the automatic cut-oft H, to admit steam to the water-flow in quantities proportional to said flow, but nevertheless modified by the optional cut-ofl', as aforesaid. It is manifest that the amount of steam-passage to a given opening of the automatic cutoff H may be made greater or less by the position given to the optional cut-off J. By these means steam heat is economized, being consumed only as wanted, and when wanted.

The oscillations of the cut-ofl' J may be limited by any suitable device-such, for example, as a pin, K, in the walls of the steamthimble O, that occupies a slot, L, in the side 8 5 of the optional cut-off thimble. Escape of steam around the rod I may be prevented by a stuffing-box, M, or other suitable means.

The external extremities of the stems D and I are provided with suitable handles, N '90 and 0.

Gaskets P and R secure complete closure of the water and steam inlets, respectively, when the faucet is shut. The gasket P is held between the thimble F and collar Q.

S represents the discharge-spout.

The above-described illustration of my invention is susceptible of various modifications. For example, the optional cut-off J may be associated with various forms of waterwith a rotary stem, D, and a disk-valve, H.

cook proper. Thus the cook proper may conwater-valve F, provided with cut-off H, and 10 sist of a plug, F, having a rubber projection, the handled out-off O J, substantially as set F, Figs. 3 and 4, and this may be associated forth.

In testimony of which invention I hereunto I claim as new and of my invention set my hand.
